I work with Vaadin framework. I'm tried to run this project with tomcat:run -Dmaven.tomcat.port=8084 I get this error:

Does anyone know where the error is coming from ? Do I have to exclude something from the dependencies ? Help!

<dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>
        **<scope>provided</scope>
        <exclusions>
            <exclusion>
                <groupId>javax.servlet</groupId>
                <artifactId>servlet-api</artifactId>
            </exclusion>
        </exclusions>**
    </dependency>

The highlighted (enclosed between **) is what I added to the pom.xml's existing dependency and the issue got resolved
